1. When i try to zoom in on a planet it zooms in to a certain point then stops. When i press the zoom key again it doesnt zoom in it just creates a landing point and the zoom is really far out and the planet is still a dot.
That sounds like a bug.
2. When i change the name of a star, the star turns into a giant planet orbiting the galaxy and planets dont orbit it unless you "Auto orbit" them.
That also sounds like a bug.
I haven't experienced any of 1 and 2.
3. How do you apply textures to objects
Put a texture file in .png, .jpg (or other common format) into the Media folder in the Documents/Universe Sandbox folder (I think that's the location, but I can't check it currently). Then open the program, click a body and on the "window"/menu which opens on the right when you click it. In one of the submenus, there is a text field for applying a texture. Type the filename of the texture, including its file extention (like .png). When it's typed or you click enter, it should be applied to the body if it's typed correctly.
4. What program do i need to use to create the models and what file type (Extension) should they be.
I think they are .dds, but all programs I can remember I've seen which can make this format aren't free. Maybe there is a converter which can convert .skp files from Google SketchUp (which is a free 3D model editor) to .dds.
5. I cant save as i go. It just creates a whole bunch of saves that you lose track of. I have to create my whole system in one go. Is there a save overwrite feature? If not is there one in the works...
I don't think there is an overwrite feature. The best solution currently is to keep the time, which it automatically adds to the save name, and then change the rest of the save name ("My system" or whatever it calls it) to whatever you want to call your system. Then you would end up with a folder like this:
Ring Distortion 20111006-151447
Spiral Galaxy 20111006-151205
Spiral Galaxy 20111006-151529
And you would know that the newest version of "Spiral Galaxy" is the lowest one in the folder, if it's sorted by name.
6. I cant fly around freely. I can only zoom in and out. GO left and right. Go up and down. The camera is always locked on to a single point. SOmetimes when i deselect an object it creates a small square called "Absolute space" that is 1 Centimetre...
I don't think you can move around freely, but you can focus on bodies by double-clicking on them. In the top, there is an area saying what you're focusing on.
7. Who put the ring from Halo in this program lol...
There's also a sim with the Death Star orbiting Endor. Probably Dan.
